Write an equation of the line that passes through (0,9) and is perpendicular to the line y = -x + 1

slope of y = -x + 1 is -1

so the slope of desired line = -(-1) = 1

equation of the line:

the reason why your question keeps getting deleted because this is not a school related question : )

i will answer your question though.

i never tried church's

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2

happy to
